1 A. HAN/V577 I E v Patented Nov. 9, 1943 UNITED STATES PATENT OFFICE VMARKING DEVICES V I Samuel AQHa mnett, Los Angeles, Calif.- 1Application December 30,1941, Serial No. 424,885 Z zclaims. (c1.loll-28) 1 This invention relates to a marking apparatus.

The general object of the invention is to provide an improved markingapparatus wherein movable type are employed and wherein novel means isprovided for holding the type in the marker.

Another object of the invention is to provide a novel type holder for amarker device.

A further object of the invention is to provide a type holding memberwherein a novel sliding sleeve holds the type holding member inposition.

Other objects and advantages of the invention will be apparent from thefollowing description taken in connection with the accompanying drawingwherein:

Fig. 1 is a top plan view of the marker body;

Fig. 2 is a section taken on line 22 of Fig. 1;

Fig. 3 is a top plan view of the jaw member;

Fig. 4 is a section taken on line 44, Fig. 3;

Fig. 5 is an end view on an enlarged scale showing the sleeve member;

Fig. 6 is a section taken on line 66, Fig. 5.

Fig. '7 is a section taken on line 1-1, Fig. 5.

Fig. 8 is a section taken on line 88, Fig. 5.

Fig. 9 is a perspective view showing the type member on an enlargedscale;

Fig. 10 is a perspective view with parts broken away showing the markingdevice;

Fig. 11 is a fragmentary, central sectional view, showing the devicewith the jaw closed;

Fig. 12 is a view similar to Fig. 11 showing the jaw open; and I Fig. 13is a sectional detail showing the spring pressed type engaging member.

Referring to the drawing by reference characters, I have shown myinvention as embodied in a marking device which is indicated generallyat It). As shown the device includes a body member H which includes ahandle l2 and a type holding portion l3.

The portion I3 includes a recess M which has parallel side walls l5 andan end wall l6. At the inner end of the recess I4 I provide opposedarcuate grooves H. In the end of the groove I1 I arrange a supportmember [8 the forward end edges of which are rounded as at I9 and are ofa size so the body I3. The tongue tapers upwardlyas at 28 and thusprojects above the plane of the body l3 as shown in Fig. 11. The jawmember includes a second bead 29 which is arranged to fit in a groove 30in a type member 3|. The type member may have a character 32 on the endthereof such as a number or a letter.

When the jaw member is in the position shown in Fig. 11, the bead 29fits the groove 3|] so that.

the type member is held in place. When the jaw member 22 is in theposition shown in Fig. 12 the bead 29 is withdrawn from the groove 30 sothat the type member 3| may be removed.

In order to provide means for operating the jaw member I provide asleeve 33 which includes a top 34, a bottom 35 and ends 36. The top isprovided with a slot 31 best shown in Fig. 7 and which includes a rearportion 38 and wider front portion 39. The portion 38 receives thetongue 26 on the jaw 22 when the sleeve is in advanced position. Whenthe sleeve is in its rear position the tongue 26 enters the portion 39of the slot. This front portion 39 has a bevelled face 40 which engagesthe tongue 26 and forces the iimer end of the tongue downwardly thusrocking the jaw about the bead 25 to the position shown in Fig. 12.

In order to hold the sleeve in its forward position I provide the bodyI3 with a hole which includes a large upper portion 4|, a reducedintermediate portion 42, a second intermediate further reduced portion43, and an enlarged lower portion 44. The hole receives a pin memberwhich includes a head and a shank 46. The head 45 has a sliding fit inthe hole portion 4| and the shank 46 has a sliding fit in the holeportion 43. A collar 41 engages the shank 46 and is disposed in the holeportion 44 andis secured to the shank to hold the parts assembled. Aspring 48 surrounds the shank 46 and urges the head 45 upwardly where itis in the path of movement of the sleeve 33.

To move the sleeve the head portion 45 is depressed so that the sleevemay be moved rearwardly. As the sleeve member moves rearwardly thebevelled portion 40 engages the bevelled portion 28 of the tongue 26 onthe jaw member and rocks the jaw member to the position shown in Fig. 12in which position the type members 3| may be inserted or removed afterwhich the sleeve is moved to its advanced position whereupon the head 45of the pin member is urged outwardly by the spring 48 thus preventingaccidental movement of the sleeve.

In order that all the type members may be.

urged together I show type holding portion l3 as provided with anaperture 50 in which a ball 5| is arranged. The ball is urged inwardlyby a relief spring 52 which is disposed in a slot 53 in the type holdingportion.

From the foregoing description it will be apparent that I have inventeda novel marking device which can be economically manufactured and whichis sturdily constructed and is highly eflicient for its intendedpurpose.

I Having thus described my invention, I claim:

1. In a. marking device, a body member including a handle portion and atype holding portion, the type holding portion having a recess adaptedto receive a type member, a jaw member pivotally mounted upon said typeholding portion, said jaw member having a, rearwardly projecting ceivingsaid jaw tongue, the wall of the sleeve defining said groove having abevelled end adapted to depress the tongue when the sleeve is moved toone position and means to normally prevent rearward movement of thesleeve to said one position.

2. In a marking dvice, a body member including a handle portion and atype holding portion, the type holding portion having a recess, a jawmember pivotally mounted in said recess, said jaw member having arearwardly projecting tongue, said tongue having a bevelled face, asleeve slidable on said type holding portion and engaging said jawmember, the inner wall of the sleeve havinga bevelled portion adapted toengage the bevelled face, on the tongue and depress the tongue when thesleeve is moved to one position andmeans. tonormally prevent movement ofthe sleeveuto said one position.
